Chrysene + Triphenylene

In the samples Chrysene and Triphenylen are analysed together as sum of both compounds.

Chrysene occurs in fossil fuels and is a product of incomplete combustion. It is used in the production of UV-filters, paints and sensitizers as well as in fluorescence labelling.

Emissions into the environment are mainly caused by human activities, e.g., coal combustion, gasification, exhausts of gasoline, diesel and kerosene engines, wood burning stoves, waste incineration and emissions from metal-working industries.
Chrysene is found in fruit and vegetable from areas with high atmospheric burdens and soil contamination, in smoked and charbroiled food, and in meat with high fat content.

In the atmosphere it is adsorbed to particles and enters soils and surface waters through wet and dry deposition. Degradation is slow and it accumulates in the environment. The bioaccumulation potential of chrysene is high.

Chrysene is one of 16 PAHs which were included in the U.S. EPA-list of Priority Pollutants and is on the EU-list of PAH recommended for monitoring.

Triphenylene occurs naturally in fossil fuels and can be extracted from coal tar. It is a ubiquitous product of incomplete combustion and is found, e.g., in exhausts from engines, tobacco smoke and food and water which have been exposed to exhausts.

In laboratory tests, triphenylene is mutagenic. Due to lack of data, carcinogenicity and other toxic effects can not be evaluated.
